CONDS. 329 



tunclis, spinl elevata, acutangulat&, ad angulum anfractuum nioni- 

 lifera, anfractibus supra angulum laevigatis. — More fusiform and 

 more finely sculptured than C. acutangulalus, the margin of all 

 the whorls coronated, in the latter respect differing from C. pm- 

 celltns, in which they are quite smooth. 



4-36. archetypus, Crosse, (f. 645, and as C. daucus, var. f. 330). 

 — There can be no doubt that the shell figured in plate 14, as 

 a variety of C. daucus, is identical in character with the one 

 figured in the French journal. The oblong-square markings and 

 the more rounded angle of the upper edge of the whorls sufficiently 

 distinguish both specimens from C. daucus. 



437. cordigera, Sowb., (as C. nobilis, pi. 21, f. 498). — C. 

 quam C. nobilis supra et infra medium magis inflatus, infra angu- 

 lum subrotundus, maculis cordiformibus albis approximatis, sub- 

 longitudinalibus, non linea rubra marginatis; spirse anfractibus 

 magis planulatis, apice albo. — The two shells which, in all the 

 great collections and all the books, have been placed side by side 

 as varieties of C. nobilis, appear to me to be exceedingly distinct. 

 The four or five points of difference are quite constant, and I have 

 never seen a shell intermediate in respect to any one of them. — 

 The apex is always pink in C. nobilis, and white iu C. cordigera. 

 The former has its heart-shaped white spots bordered with a 

 line of strong colour on the front side, the intervening spaces 

 are wide, and crossed by articulated lines, the outlines of the 

 shell are straight, and in each of these particulars C. cordigera 

 differs from it. 



438. concinnus, Sowb. — C. subpyriformis, lsevis, infra sul- 

 catus, solidus, purpurascens, spiraliter lineis interruptis cincta, 

 anfractuum margine acuto distauter nigro-puuctato. — A smoother 

 and neater shell than C. punctatas. 



439. Borneensis, Sowb., (f. 648). — C. subcylindrica, oblongo 

 infra attenuatus, sulcatus, supra subintlatu, lrevis, obscure fulvus, 

 rubro obscure fiarnmatus, apertura intus purpurea, margine ma- 

 culate — The only specimen of this shell we have seen is in the 

 collection of T. L. Taylor, Esq. 



440. Pazii, Bern., (f. 649). — C. crassus, turbinatus, obtuse 

 angulatus, albidus, fasciis quater latis castaneis cinctus, medio et 

 ad margiuem superiorem maculis quadratis tessellatus. — At first 

 sight this would appear to be one of the numerous varieties of 

 C. venulatus, but the tessellated character caused by the white 

 lines cutting off and defining the square spots, is perhaps suffi- 

 cient to distinguish it.
